About

About EverClean

EverClean uses robotic hull crawlers to remove early biofouling during frequent, planned cleaning visits. The robots attach to the submerged hull, follow controlled paths and clean the coating while capturing visual and operating data.

Greensea IQ delivers EverClean as a managed service, scheduling work around vessel operations and maintaining a continuing hull-condition record. Ship operators receive cleaning reports and performance information through a digital portal. Recurring treatment supports fuel efficiency, emissions reduction and invasive-species management across commercial fleets.

Context

Market context

Robotic hull-care service for underwater inspection, grooming and maritime maintenance.

  • Target environment: Commercial vessels, defense fleets, ports, maritime maintenance programs and underwater asset-care workflows.
  • Workflow context: Hull inspection, recurring grooming, underwater maintenance, vessel-performance support and below-waterline data capture.
  • Customer context: Ship operators, maritime maintenance teams, naval fleets and asset owners managing hull condition across vessels.
  • Deployment model: Service model built around underwater robotics, Greensea IQ software and recurring hull-care operations.
  • Commercial maturity: Commercial maritime hull-cleaning service with product positioning around underwater cleaning operations; hardware depth should remain subordinate to the service model.
  • Adoption constraints: Adoption depends on port access, vessel scheduling, service coverage, inspection requirements, fouling conditions and trust in robotic hull-care results.
  • Market position: Maritime robotics service focused on recurring hull performance rather than one-off ROV inspection.
  • Adjacent products: Armach hull service robots, ROV hull inspection systems, maritime inspection robotics
